PF3D7_0302500 cytoadherence linked asexual protein 3.1

Upper 2 rows: Localization of Pf34 to the rhoptries was demonstrated in late stage parasites by immunostaining infected blood smears with anti-Pf34 and co-localising with either anti-RAMA or anti-RhopH3 (both rhoptry markers) or anti-AMA-1 (microneme marker) antibodies.

Lower row: A mature schizont (i) and two extracellular merozoites (ii) showing the close apposition of Pf34-positive (green) and RAMA-positive (red) structures in the apex of the merozoite. Panels (iii) and (iv) show the apex of merozoites and the two rhoptries connected to the Pf34-positive structure at the anterior when visualised by confocal microscopy. N, nucleus; R, rhoptry. Bars represent 1 mm in (i) and (ii) and 500 nm in (iii) and (iv).
